    I came across this ski on youtube a while back. I"m glad I found the build thread where I can track the progress.

    How does the new manifold fit? I had been looking into getting one.

    Are you running an updated tune?

    Fits great had to move all my electronics because of how much further out the intake comes off the engine. Wouldn't be an issue in an stx. The ECU is off a 2016 stx I am not messing with the tune on it I'm just going to adjust the fuel pressure regulator to compensate for the greater air flow. Also because it's plastic I this it will help cooler intake temperature. I have a built engine coming for it very soon I give more details one I have it.

    Here we go now I'm getting somewhere. 68.1 mph at 7570 rpm this was with just under 1/2 a tank of gas. I'm going to try it again when I get the low fuel light to come on. Also this is still with a 13/19 skat trak prop.
